AUTOMATIC ENVELOP-SEALER AND STAMP-AFFIXER.

SPECIFICATION forming part of Letters Patent No. 695,408, dated March11, 1902.

Application filed March 27, 19 01.

To all whom it may concern:

Be it known that I, LoUIsMADAs, a citizen of the Empire ofAustria-Hungary, and a resident of New York, borough of Manhattan, 5 andState of New York, have invented certain new and useful Improvements inAutomatic Envelop-Sealers and Stamp-Affixers, of which the following isa specification.

This invention relates to a device for sealing and stamping envelopsautomatically and simultaneously.

The object of the invention is to provide a device of this character inwhich 'theoperations of sealing and stamping envelops are done in asimple, effective, more rapid, and less objectionable manner than doingthe same by hand/ v To this end theinvention consists of an automaticenvelop-sealer and stamp-affixer comon a suitable stand, a feed-belt,power-transmitting wheels, rollers and belts, nioisteningpads formoistening the mucilaged edge of the envelop-flap and the stamps, meansfor supcompression-rollers for pressing the moistened envelop and stampin a manner which will be more fully described hereinafter and finallypointed outin the claims, reference 0 being had to the accompanyingdrawings, in

which- Figure 1 is a side elevation of the automatic envelop-sealer andstamp-affixer. Fig. 2 is an elevation of the opposite side thereof. Fig.

3 is a plan view of the device. Fig. 4 is a front view thereof. Fig. 5is a detail view of the stamp-moistening rollers. Figs. 6 and 7 areviews of the moistening-pads. Fig.8 is a cross-section of a pad on line8 8, Fig. '7;

40 and Fig. 9 is a View of part of the feed-belt, showing the means forengaging each envelop to be carried forward for sealing and stamplng.

Similarletters of reference indicate corresponding parts.

Referring to the drawings, 20 represents the base of the device forautomatically sealing and stamping envelops. Secured firmly to the basew are the standards t, which support the envelop-receiving box 8 and thepower- Serial No. 53,088. (No model.)

transmitting mechanism. The envelop -receiving box is supported in aninclined position being higher at the front end,and provided with themovable partitions g 9 At each end of the long partition g and the outerend of the partition g is provided a screwg which projects through theslot 8 in the sides of the box'and clamps by means of the thumbscrew thepartition in any desired position, so as to accommodate large or smallen velops, as desired.

The rollers a and a are arranged, respective'ly; at the rear and frontend of the envelop-receiving box 8 adjacent the bottom of the same andare connected by the feed-belt z, the upper length of which lies withinthe bottom of the box along one side thereof and .issupportedapproximate the center by the roller T The shaft upon which the roller ais secured is provided at one end with the pulleys i and 7c and at theopposite end with thepulleys 70, I0 and i.

The driving-wheel I), mounted onthe hanger b of the standard t, connectsby the belt I) with the pulley t, which imparts rotarymotion to thepulleys and roller on the shaft a. The compression-rollers d and e,mounted at the front end of the device one above the other, are rotatedin opposite direction by means of the pulleys c and h, arranged atopposite ends of rollers d and e. Adjacent the pulley h is mounted theshaft g, to the outer end of which is secured the wheel j, connected bythe cross-belt f with the pulley t on the shaft a.

The roller g is provided at the in- 8 nor end of the shaft g. andcooperates with the moistening-roller h. These rollers rotatein'opposite direction by means of the gearwheel Z, transmitting motionfrom the shaft g. The moistening-roller h is covered with thewater-reservoir n is secured in an eletoo vated position at the upperedge of the front of the box .9.

Under the sponge-box Jcthe moisteuing-pad m for moistening the mucilagedflap of the envelop is secured at one end to the slidable support at,which is adapted to slide in the Way m, provided on the base 20. Themoistoning-pad consists of a sheet-metal holder m, formed withturned-back edges for holding a sponge. The front is provided with asharp edge, so as to engage the flap of the envelop in order to moistenthe same. The moisteuing-pad is inclined from the supporta to a higherpoint at its outer end and is arranged with the sharp edge nearest thefront of the box .9 and with the sponge side opened on the under side.Water is supplied to the moistening pad m from the reservoir a throughthe tube n In order to maintain the flap of the envelop in contact withthe sponge while the envelop is passing outof the box, thesupportinglingern is secured to the support at under the moistening-pad.The chute o is secured at its upper end to the front of the box .9, andits lower end projects outwardly to a point above the rollers g and 71..The feed-belt .2 is connected at its ends by the plate 1), to which issecured the finger p for engaging the envelop to be carried forward bythe feed belt for sealing and stamping.

According to the size of the envelops to be sealed and stamped theslidable partitions g g are arranged in the box to provide for receivingthe same. The en velops are placed between the partitions and the frontof the box 8 singly or in a pile, each envelop arranged with its flapside downward and the flat edge adjacent the side of the box.

The device .is set in motion by turning the crank b of the driving-wheelb, which transmits motion to the roller a and the pulley on the shaft athrough the belt o The roller a operates the feed-belt .2", the belts cand 71 .operate the compression-rollers (Z and e, the belt f" operatesthe moistening and feed rollers h and g, and the belt 7;. operates thesupporting-roller 0' In operating the device the finger p of thefeed-belt .2" engages the bottom envelop of the pile and carries itforward through an opening provided in the front of the box at thebottom thereof. As the envelop is carried through this opening, thesharp edge of the moistening-pad engages the flap and the finger npresses the mucilaged surface in contact with the sponge. The stamps arefed singly through the chute o and pass between the moistening and feedrollers g and h to be dropped upon the envelop. The stamp is fed intothe chute simultaneously with the advance of the envelop, so that thestamp will drop upon the same at the proper point and time. As theenvelop is carried forward, having at the same time the flap moistenedand the stamp deposited, the same passes between the compression-rollersd and e in order to set the flap and the stamp to the envelop. Theseoperations are performed in one contin uous feed of the envelop from thebox.

When it is desired to stamp envelops Without sealing them, themoistening-pad is shifted to one side in the way on, so as to be out ofoperative relationship to the other part of the machine.

The advantage of the device resides in tho effectual manner in whichenvelops can be simultaneously or separately sealed or stamped as theoperator desires.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An automatic sealing and stamping de vice,consisting of an envelop-receiving box, means for feeding envelopstherefrom, means for moistening the flap of the envelop,a stampchute,means for moistening the stamp and dropping the same upon the envelop,and compression-rollers for setting the stamp and flap of the envelop,substantially as set forth.

2. An automatic sealing and stamping machine, consistingof anenvelop-receiving box, a feed'belt having means for engaging andcarrying forward the envelop, means for operating the feed-belt, amoistening-pad for moistening the flap of the envelop, a stampchute,means for moistening and feeding the stamp to the envelop, and compression-rollers for setting the stamp and flap of the envelop,substantially as set forth.

3. An automatic sealing and stamping device, consisting of anenvelop-receiving box, means'for feeding the envelops therefrom, amoistening-pad, a supporting-finger under said pad, a stamp-chute, amoistening-roller and feed-roller cooperating therewith,compression-rollers, and means forimparting motion to the feed-belt,moistening-roller and compression-roller, substantially as set forth.
